Getting "Full Performance" From My V85 TT

[Paultergeist]

Greetings,

The V85 TT "Use+Maintnenace Book" (page 146) states the following:

"The full performance of the vehicle is only available after the service at the end of the running in period."

I am trying to gain some understanding of what this exactly means.  Is this basically a message to me -- as the rider -- to continue to ride the bike rather gently until the mileage and recommended initial service is completed?  Is there -- conversely -- a trigger-point programmed into the ECM to adjust fueling/timing etc. once the odometer passes the break-in mileage?  Or.....is this some sort of map download/install which only a dealer can do -- in which case I may need to ensure that the dealer service department knows about this and gets it done.

Is there some means by which I myself can *know* that my bike is operating with its' "full performance?"

Thanks for any clarity.

There is not ECU limiting factor it's just the manufacturers semantics nudging you to take it easy until after the first service and it's had SOME running in. It's as much for the manufactures benefit as the owners of course.

On my new Triumph Tiger 900, the tacho would change colour as a reminder to "take it easy".
This changed after the first service update, I didnt notice any change in performance or economy.
So ride it, dont lug it dont thrash it.
Enjoy.

If an engine is manufactured properly using modern techniques it needs nothing more than to reach operating temperature  before using all the performance...

In the owners book on my 84 LM3 it states after 1st service to gradually increase until maximum permissible limits.  Also talks about be careful of it's kicking-up abilities.

The V7III has a shift  that flashes at the break in RPMs.  Does the V85tt have that too?

[blu guzz]

Yes, the v85 has the shift lights.  They are adjustable though so you can orient them to the actual red line.  I find them handy as they do catch the eye when approaching redline.

My understanding from the OP is , it is ok to wick it up after the engine break in. Back in the old days there was a school of thought that if you broke a new bike in hard it would always run hard. Can’t say if there was any truth to it.  But I always took it easy on the first 500mi on a new engine build before I let it rip, with no problems.

[Perazzimx14]

Just ride it like you normally would. Its not a Faberge egg or a leather jacket its a modern engine that has had 99% of the breakin done before the motor was ever in the bike when it was bench tested for a few seconds.

A vast majority of riders could not use all the performance a a 25HP Ninja 250. Even less can use all the "potential" of anything bigger. If your bike only ever got to 90% of it "max" potential it will still be far more than will ever likely be used unless WOT on a straight away.....yawn. Anything else you'd never know.

Ride the bike like an old lady going to Sunday service or ride it aggressively and in the end there will be no difference in how it performs or its service life.

Hi guys, been awhile since I have posted, been distracted with an Italian dual purpose bike i purchased with 1.4 miles on the odometer.
The speedo on the dash will record your performance of each ride. As I scrolled thru the various functions I noticed the highest speed recorded was 72MPH!
When I asked the seller why he had taken the brand new bike 72 mph (close to wide open throttle), he informed me it was like that when he purchased the bike.
The service manager told him if the engine is going to detonate they would rather have it done prior to the customer picking the bike up.  He added that by running the engine with a full load it will help the compression rings seal better. 
Being a bit skeptical I did a little research and came across a study which compared two identical engines.  One was broken in according to manufacture specs (very gentle), and and one which was run like they stolen.  After the "break in period", both engines were disassembled for comparison.   Neither engine showed any appreciable difference in wear. In fact the engine run the hardest showed less carbon build up in the ring grooves indicating they were actually sealing better than the mild break in.These new engines and materials aren't anything like the engines of old.

I have always run my bikes in a sporty way from the get go, even the harleys and have never had issues.  I have friends that are scrupulous about break in and that gives them comfort, so good on them.  It's just a few good afternoon rides to get to the break in mileage anyway. 

[bad Chad]

I wouldn't sweat it Thunderbolt.   I saw that comparison as well, but I don't put much stock in the science behind it.  Comparing two engines is pretty much meaningless.  Now if the guy was able to compare 100 identical motors and instead of two, it might tell us something, but that can get kind of pricy!!

You're lucky I wasn't the service manager, I'd have been on the floor in hysterics. What do you think happens to new bikes off the production line? They get an old lady in from the local church to gently ride them in the test cell off the production line

If recent forum history is any proof.  It doesn't matter on the break-in procedure that's chosen.  What matters is if the owner riding his bike is extracting the rpms out of the engine.  Higher rpms is always better for the Moto Guzzi vee.

Just about every mass produced engine made these days is either run on a dyno before instillation or more usually run on a dedicated rig by either air or more commonly an electric motor and all the parameters such as volumetric efficiency, cylinder pressure vibration oil pressure etc need to within tolerance. The process also helps with initial stages of ring break in. Not full but initial. The ring break in is the critical part of the break in process and requires cylinder pressure to achieve the desired result so babying the engine around at lowish rpm with small throttle openings and so low cylinder pressures inhibits ring break in. With engines these days you simply ride them around normally preferably not commuting work or freeway droning and stay away from the upper rev range and lugging for the first 1000klm then its whatever you like.
Changing the oil and filter out in the first 200klm is also a good idea to remove the initial wear material from the rings then again at 1000klm.

Shift at 5k rpms and cruise above 4k rpms.  Anything lower and performance suffers.

Pretty sure somewhere in the documents you will find that they recommend not exceeding a certain lower than redline RPM for the first 900 miles.  It was on my 2020 travel
